My suggestion for the windmill hut, although it didnt do this in the original game, would be to have the windmill spin at a moderate spped. Then, maybe every minute or more, or even less, have it stop to where the two side platforms are on screen and can be stood and fought on. This would give the stage some versatility and make it fun too. Also, while the stage is spinning, there could be no way to die, giving players a chance to accumulate damage. Then, when the spinning stops again, players can be killed from either the entrace to Dampe's grave, and you could even throw your own twist on the age by adding another doorway on the otherside where players can be killed. I don't know how you feel about this idea, or how difficult it would be to implement. I know nothing about stage hacking, just a suggestion
